CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 248,245, dated October11, 1881.

Application filed July 12, 1881. (No model.)4

To all whom it may concern: Be it known that I, ALBERT Woon, of Milford,county of Oakland, State of Michigan, have invented a new and usefulImprovement in Car-Couplers; and I declare the following to be a full,clear, and exact description ofthe same, such as will enable othersskilled in the art to which it pertains to make and use it, referencebeing had to the accompanying drawings, which form a part of thisspecification.

` My invention consists in the combination of devices and applianceshereinafter specified, and more particularly pointed out in the claims.

In the drawings, Figure l is a longitudinal central section of a deviceeibodyiug my 'iiivention. Fig.2 is a side elevation of the same, showingit as attached to a car.

A is a car; B, its draw-head; C, the coupling-link. f

D is a detaining-shoulder, which receives the strain of the link. It isbeveled upon the entering-face l to guide the link overits crest.

E is a lockingbar, connected by a link, c, with the rock-shaft E. is aneccentric, E2, and a lever-arm, E3, which projects back between thecars.

F is a lever, pivoted at f to the draw-bar. One end of this lever iscontiguous to the eccentric E3, and the vother end has a lug, F', whichprojects up beneath the link.

The operation ofthe device is as follows:

When it is desired to couple the cars the entering-link presses back thelocking-bar and slides down its face e into its position back of theshoulder D. As soon as it has dropped clear of the bar E the weight ofthe arm E3 causes the har E to plunge forward over the link and lock itin place, so it cannotjump out of connection.

When it is desired to uncouple the cars the vbrakeman draws upon achain, G, or othe'rwise lifts the lever E3. This causes the bar E torecede, and the eccentric E2 presses down the lever F, causing the lugF- to rise and lift Upon this rock-shaft the end of the link clear ofthe shoulder D,

when it will draw out.

I would have it understood that the shoulder D may be solid, as shown;but it may be in the nature of a removable block, or the shoulder may befaced at its rear with a block or pin of iron or steel, and the surfacemay, if necessary,A be case-hardened or cast with a chill. So also,instead of a chain, G, a rod may be employed or an arm may extend toth'e side of the car, by which the lever E3 can be lifted. The eccentricE2 is so adjusted with relation to the lever F that it willvnot depressthe lever and raise the link until the locking-bar has been nearly orquite withdrawn.

The rock-shaft may, if desired, be extended out to the side of the car,and be there provided withan arm, E3.

What I claim is A l. A car-coupler consisting of the combination, with adraw-head, of an engaging-shoulder, a locking-bar, D, anddisengaging-lever F, the said locking-bar and disengaging-lever governedby a weighted lever, E3, substantially as described.

2. The combination, with the shoulder D, of the locking-bar E, lever F,eccentric E3, and arm E3, whereby the coupling-link is locked andreleased, substantially as described.

3. The combination of the lever F, the eccentric E2, arm E3, the wholeconstituting a .means whereby-the coupling-link is lifted free from theshoulder` D, substantially as described.

4. The combination, with the shoulder D, locking-bar E, lever F, and armE3, of a chain or rod, G, whereby the device may be uncoupled from theinterior, top, or side of a car, substantially as described.

In testimony whereof I sign this specification in the presence of twoWitnesses.

ALBERT WOOD.
